Ductile Iron Casting

The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed. The steps in this process are described in greater detail in the next section. In sand casting, the primary piece of equipment is the mold, which contains several components. The mold is divided into two halves - the cope (upper half) and the drag (bottom half), which meet along a parting line. Both mold halves are contained inside a box, called a flask, which itself is divided along this parting line.

Advantages of Ductile Iron Casting :
- Ductile Iron Casting provides Higher Tensile Strength
- Less Deflection Under Load Conditions
- No Straightening Required in Most Instances
- No Problems With Hot Tears and Cracks
- Good Machinability
- Easier Feeding of Difficult Designs

Ductile Iron Casting is particularly well suited for :
- Valves
- Pump - Gears and Rollers
- Spring Hangers
- Suspension Parts
- Wheel Hubs
- Bearing Caps
- Hardware
- Universal Joints
- Threadless Connectors and Flanges
- Various Automotive and Agricultural Items.
